Standard Bank Overall Servives

Standard Bank phoned me for a credit card, they cant even get a residential address right after 10 attempts to change it, I can't apply for anything at standard bank due to there incompetence, then you get 10 calls from standard bank survey department to find out how are there service what service?. I have to go into the back again to change my residential address that i have changed 10 times before to apply for a overdraft, what service do they really provide.
